the two devices.
Layer 2 switching
VLAN support and tagging
supports IEEE 802.1Q (4,094 VLAN IDs) and 256 VLANs simultaneously
GARP VLAN Registration Protocol
allows automatic learning and dynamic assignment of VLANs
Jumbo packet support
improves the performance of large data transfers; supports frame size of up to 9220 bytes
IEEE 802.1v protocol VLANs
isolate select non-IPv4 protocols automatically into their own VLANs
Rapid Per-VLAN Spanning Tree (RPVST+)
allows each VLAN to build a separate spanning tree to improve link bandwidth usage; is compatible with PVST+
Layer 3 routing
Static IP routing
provides manually configured routing; includes ECMP capability
Routing Information Protocol (RIP)
provides RIPv1 and RIPv2 routing
256 static and 2,048 RIP routes
facilitate segregation of user data without adding external hardware
Security
Multiple user authentication methods
IEEE 802.1X
uses an IEEE 802.1X supplicant on the client in conjunction with a RADIUS server to authenticate in accordance with
industry standards
Web-based authentication
provides a browser-based environment, similar to IEEE 802.1X, to authenticate clients that do not support the IEEE
802.1X supplicant
MAC-based authentication
authenticates the client with the RADIUS server based on the client's MAC address
Authentication flexibility
Multiple IEEE 802.1X users per port
provides authentication of multiple IEEE 802.1X users per port; prevents a user from "piggybacking" on another user's
IEEE 802.1X authentication
Concurrent IEEE 802.1X, Web, and MAC authentication schemes per port
switch port will accept up to 32 sessions of IEEE 802.1X, Web, and MAC authentications
Access control lists (ACLs)
provide IP Layer 3 filtering based on source/destination IP address/subnet and source/destination TCP/UDP port number
Source-port filtering
allows only specified ports to communicate with each other
RADIUS/TACACS+
eases switch management security administration by using a password authentication server
IEEE 802.1X, MAC or Web authentication
provides concurrent network access control and Web authentication of up to 24 clients per port
Secure shell
